SUMMARY
Penelitian ini bertujuan untuk memperoleh modul berbasis kontekstual yang sesuai dengan kriteria penilaian Badan Standar Nasional Pendidikan (BSNP) dan mengetahui hasil belajar siswa yang diajarkan menggunakan modul yang dikembangkan. Penelitian ini dilakukan di SMA Panca Budi Medan. Sampel dipilih secara purposive sampling untuk mengambil satu kelas yang digunakan sebagai kelas eksperimen. Jenis penelitian ini adalah penelitian pengembangan Research and Development (R and D) dengan One Group Pretest-Postest Design. Modul yang dikembangkan dinilai menggunakan kuesioner validasi dari BSNP, sedangkan data untuk hasil belajar siswa diperoleh dari tes yang menggunakan instrument tes objektif sebanyak 20 pertanyaan yang telah diuji validitasnya, realibilitas, tingkat kesulitan, daya beda dan distruktor. Berdasarkan penilaian validator ahli ditunjukkan bahwa modul yang dikembangkan memenuhi kriteria BSNP dengan kriteria yang valid dan tidak perlu direvisi. Hasil belajar kimia siswa menggunakan modul yang dikembangkan mendapatkan nilai yang lebih tinggi dari nilai kriteria ketuntasan minimum (KKM) berarti modul yang dikembangkan layak digunakan di SMA/MA. The research we conducted aims to obtain contextual based modules that are in accordance to the assessment criteria of the National Education Standards Agency (BSNP), and then the learning outcomes of students taught using the modules developed will be measured. This research was conducted at Panca Budi High School Medan. The sample was selected by purposive sampling to take one class used as the experimental class. This type of research belongs to the type of Research and Development (R and D) with One Group Pretest-Postest Design. The modules developed were assessed using a validated questionnaire from the BSNP, while the data for student learning outcomes were obtained from tests using objective test instruments as many as 20 questions that had been tested for validity, reliability, difficulty level, different power, and destructors. Based on the expert validator's assessment it was shown that the module developed fulfilled the BSNP criteria with valid criteria and did not need to be revised. Chemistry learning outcomes of students using the developed module get a higher value than the minimum completeness criteria (KKM), meaning that the module developed is suitable for use in the high school level.
